Description
We revisit inclusive $J/\psi$ and $\Upsilon$ photoproduction at lepton-hadron colliders, namely in the limit when the exchanged photon is quasi real. Our computation includes the next-to-leading-order (NLO) $\alpha_s$ corrections to the leading-order contributions in $v^2$.
We consider first large-$P_T$ inclusive photoproduction of $J/\psi$ at HERA and provide NLO predictions for the EIC (Phys.Lett.B 811 (2020), 135926).
Then we focus on the total inclusive $J/\psi$ and $\Upsilon$ photoproduction cross sections at NLO all the way from AMBER to FCC-eh energies, passing by those of the EIC and LHeC. We investigate where such measurements could be used to improve our knowledge of gluon densities at scales as low as a couple of GeV (e-Print: 2112.05060 [hep-ph]).
